Here is my latest AR Pistol build, I even did the Cerakote work. It shows in some places, but I'm not trying to win any awards. It sucks that I'm going to have to register it as an assault weapon. Won't be able to take it to the range right away because I'll be traveling

What would happen if you shoot it in folding positio ? Would bcg pop out through the back ?

No, the carrier would not pop out but the folder would likely be damaged. There is a clear warning on the folder to close before firing. There is a youtube video of a guy firing with the folder in the open position just to see what would happen.

There are some articles professing that the Gen 3, the one I have, the only version sold now, is designed to fire a single shot. The gen 2 was mostly aluminum while the Gen 3 is all 4140 steel. I don't see that claim on Law Tactical's website though. Perhaps the youtube video I referenced was a Gen 2 folder and not a Gen 3.

You'll never see that claim, because of the liability of the possibility (however slim) that an AR pistol BCG will fly through someone's cheek.

Whether you can safely fire closed or not, though, that thing is really really cool. I'm about to order one myself to check it out.
